Review for Contacts Sidebar by jok111
Rated 1 out of 5 stars
I get...
"Not compatible with Thunderbird 2.0.0.16" with only the option to uninstall, no matter how many times I restart Thunderbird.
It tries to install each restart, but can't.
Got the latest add-on version.
Any help with what I am doing wrong appreciated.
